as per this bug-report from years ago

"Rather than adding it as a filter element and stealing playbin's messages, it would probably be better to add it as a tee element and use an event probe to watch for the events."

Lets investigate how the visualisation plugin does this

looking at the gstreamer spectrum example the spectrum is added after the audioconvert element.

So for thus plugin where it using "add_filter" - where does this add the element. Maybe it adds at the end of gstreamer list and hence why we see a half a second delay between a audio beat and the "spectrum beat".
